The findings indicated that normal B lymphocytes and B-CLL cells were similarly sensitive to AICAR-induced apoptosis, whereas T cells from B-CLL subjects appeared to show only minor sensitivity. Furthermore, upon exposure to AICAR, B-CLL cells appeared to have higher intracellular levels of ZMP compared to T cells. This observation suggests that ZMP accumulation may be crucial in activating AMPK and inducing apoptosis in these cells. One meta-analysis aimed to investigate the potential of AICAR on cardiovascular tissues.(2) The data was collected from 5 randomized, placebo-controlled, double-blind clinical studies. From the results, AICAR was suggested to reduce myocardial tissue infarction size and cardiac cell death and apparently improve the overall outcome of the experiment. Angiogenic balance was further assessed in the serum of pregnant rats in vitro as previously reported (17) in two separate experiments, and each was performed in duplicate.

4. Modeling Obesity, Metabolic Syndrome, and Diabetes Mellitus

  • The rate of weight gain in animals treated with HFD was significantly increased relative to the control starting from the fifth week of the study.
  • The test was carried out on half of the animals from each group the day before the planned necropsy—the amount of glucose in the blood after an overnight fast was determined in dynamics 20, 40, 60, and 120 min after insulin administration (Insulin glulisine, Sanofi, subcutaneously, 2 IU/kg).
  • However, a decrease in gluconeogenesis and an inhibition of oxidative phosphorylation (OXPHOS) can be observed in response to AICAr in mice lacking both AMPKα1 and α2 isoforms [38,39,40].
  • Additionally, the animals from group 6 were administered Methotrexate (MTX) at a dose of 1 mg/kg in parallel with AICAR, which slows down the metabolism of AICAR.

Interestingly, AICAR has been used to improve ischemia-reperfusion injury in cardiac tissue during coronary bypass surgery (7), which, unsurprisingly, may have similar effects in other tissues such as the placenta. Moreover, these specific placental ischemia-dependent mechanisms have been proposed before in in vitro models (14), but we are the first to report this effect of adenosine-mimetic administration in a model of placental ischemia-induced hypertension. These observations are further supported by our placental tissue analysis of AMPK phosphorylation, in which AICAR-induced increases in phosphorylation of AMPK were dependent on the placental ischemia induced by the RUPP procedure and not observed in the NP placenta.

AICAR Peptide and Malignant Cell Lines

AICAR was also posited to decrease the hepatic sterol regulatory element-binding protein 1c (SREBP-1c) and reduce fatty acid synthase (FAS) enzyme expression, reducing triglyceride synthesis in murine models’ livers. SREBP-1c is posited to be a protein apparently involved in lipid metabolism, primarily in liver tissues. It is a member of the SREBP family, which appears to be transcription factors that regulate the expression of genes required to synthesize cholesterol, fatty acids, and triglycerides. Therefore, it is possible that a decrease in SREBP-1c might lead to a reduction in fatty acid synthesis. It is suggested to play a role in the process of converting acetyl-CoA and malonyl-CoA, small molecules, into palmitate, a long-chain saturated fatty acid.

7. Blood Chemistry

The development of metabolic syndrome and diabetes was also confirmed by an increase in the HOMA-IR index in all the animals treated with HFD and pathological changes in biochemical parameters indicating a violation of lipid metabolism and liver function. At necropsy in the animals treated with HFD, a large number of fatty deposits in the abdominal cavity was revealed, as well as hydronephrosis of one of the kidneys. In the animals treated with HFD, there was a decrease in the mass of the liver, adrenal glands, and pancreas, as well as a significant increase in the mass of adipose tissue surrounding the epididymis. The introduction of AICAR, both alone and in combination with Methotrexate, reduced the body weight and body weight gain relative to animals on HFD, starting from the ninth week of the study. The feed intake in HFD-fed AICAR-treated animals was slightly higher than HFD-fed animals without treatment, indicating some normalization of this indicator. In the animals treated with AICAR from day 1 of the study, the fasting insulin levels did not differ significantly from the animals on STD, in contrast to the rest of the animals on HFD.

Indeed, our initial hypothesis only considered effects on VEGF via AMPK activation, since the regulation of sFlt-1 via AMPK is unclear at this point. Also, it is important to note the changes following AICAR administration on the angiogenic balance and blood pressure were only observed in the RUPP, and not NP. This further suggests a possible mechanism that is mediated by the placental ischemia and/or hypoxia.
